Pumpkin spice lattes have been available at major coffee chains for weeks already. Our friends at Experience Life break down their ingredients, and offer a homemade alternative for you to make on your own.

Starbucks introduced the seasonal treat — now known simply as the PSL — in 2003. It has since spawned a widespread cult following and countless copycats.

What exactly makes the PSL so enticing? Well, for starters, there’s about 49 grams of sugar (12 teaspoons) in a typical 16-ouncer, which contains espresso, steamed milk, pumpkin-flavored syrup, and whipped-cream topping. What’s not clear is whether the concoction contains any actual pumpkin or squash. Starbucks lists most ingredients on its site but declined to specify all the contents in its so-called pumpkin syrup.
